Purpose: To analyze this uncommon problem, we evaluated late recurrent retinal detachment in relation to the contemporary classification of proliferative vitreoretinopathy (PVR). Methods: Ten eyes of 10 patients with late recurrent retinal detachment after 1 or more years of succesful reattachment, were identified. The study group was derived from a total of 223 consecutive cases of rhegmatogenous retinal detachment repair not associated with proliferative diabetic retinopathy, uveitis, or penetrating ocular trauma.We retrospectively analyzed the clinical and operative records of one surgeon over a 6–year period to identify late recurrent retinal detachments. Results: The mean follow up after late recurrent detachment repair was 16.8 months (range, 12 to 24 months). Redetachment occurred from 12 to 56 months (average, 26.5 months) after the initial detachment surgery. Late recurrent retinal detachments were associated with new retinal breaks (7 eyes), reopening of old breaks (1 eye), or both (2 eyes). In all eyes, 16 open breaks were identified, ten of which were on or anterior to the scleral buckle. Five eyes had grade C PVR including one eye with anterior PVR, three eyes with posterior PVR, and one eye with both anterior and posterior PVR. The retina was reattached after additional vitreoretinal surgery in eight eyes; two eyes declined reoperation. Visual acuity improved in seven of eight eyes after repair of the late recurrent retinal detachment. Conclusions: Reoperation for late recurrent retinal detachments can successfully reattach the retina and improve visual acuity. Vitreous base traction seems to be an important factor in the occurrence of this pathology.
